DETAILED DESCRIPTION

Hereinafter the present disclosure will be further described in detailin conjunction with drawings and embodiments. It is to be understoodthat the embodiments set forth herein are intended to explain thepresent disclosure and not to limit the present disclosure.Additionally, it is to be noted that for ease of description, merelypart, not all, of the structures related to the present disclosure areillustrated in the drawings.

FIG. 1 is a structure view of a display panel 10 according to anembodiment of the present disclosure. As shown in FIG. 1 , the displaypanel 10 includes, in part, a base substrate 11, a first transistor 12,and a planarization layer 13. The first transistor 12 includes a firstactive layer 121, a first gate 122, a first source 123, and a firstdrain 124. The first source 123 and the first drain 124 are located onone side of the first active layer 121 facing away from the basesubstrate 11. The first gate 122 is located between the first activelayer 121, and both the first source 123 and the first drain 124. Theplanarization layer 13 is located on a same side of the first source 123and the first drain 124 facing away from the base substrate 11. In thedirection perpendicular to the base substrate 11 (the X direction asshown in FIG. 1 ), at least one insulating layer and a first organicarea 14 are provided between the film layer where the first active layer121 is located and the planarization layer 13. An insulating layer inthe first organic area 14 is made of organic material. The display panel10 includes a display area AA and a non-display area NAA. The firstorganic area 14 is located in the display area AA.

As shown in FIG. 1 , the first transistor 12 may include a first activelayer 121, a first gate 122, a first source 123, and a first drain 124.The first gate 122 is located between the first active layer 121, thefirst source 123 and the first drain 124, that is, the first transistor12 may include a top-gate structure. In another embodiment, the displaypanel 10 may further include a planarization layer 13. An insulatinglayer and a first organic area 14 are disposed between the film layerwhere the first active layer 121 is located and the film layer where theplanarization layer 13 is located. The insulating layer in the firstorganic area 14 is made of organic material. Since the Young's modulusof the organic material is less than the Young's modulus of theinorganic material and the organic material has a good bendability,compared with the related art, the beneficial effects of the displaypanel provided in an embodiment of the present disclosure are describedas follows: on the one hand, the bendability of the display panel can beimproved, and thus the bending stress can be avoided or reduced; on theother hand, if a crack occurs in the inorganic material, due to theexistence of an interface between the organic material and the inorganicmaterial, the crack may end at the interface; or even if the crackfurther extends into the organic material, since the Young's modulus ofthe organic material is less than the Young's modulus of the inorganicmaterial, and the organic material is soft and has a good toughness, itis not easy for the crack to continue to propagate in the organicmaterial. Therefore, the organic material in the first organic area canblock the crack in the inorganic material, and thus prevent or slow thespread of the crack. In this manner, a highly bendable display panel canbe formed. It is understood that the organic material in the firstorganic area can block the crack in the inorganic material in thedirection perpendicular to the base substrate 11 (the X direction asshown in FIG. 1 ), and thus prevent or slow the spread of the crack; theorganic material in the first organic area can also block the crack inthe inorganic material in other directions that intersect with the Xdirection, and thus prevent or slow the spread of the crack. Forexample, in the direction parallel to the base substrate, as long as thefirst organic area is located on the extension path of the crack, thefirst organic area can prevent or slow the spread of the crack.

It is noted that the first organic area 14 is disposed between the filmlayer where the first active layer 121 is located and the film layerwhere the planarization layer 13 is located. In the directionperpendicular to the base substrate 11 (the X direction as shown in FIG.1 ), the first organic area 14 may be partially overlapped, completelyoverlapped, or not overlapped with the first active layer 121, that is,the vertical projection of the first organic area 14 on the plane wherethe base substrate 11 is located is partially overlapped, or completelyoverlapped, or not overlapped with the vertical projection of the firstactive layer 121 on the plane where the base substrate 11 is located. InFIG. 1 , only the case where the vertical projection of the firstorganic area 14 on the plane where the base substrate 11 is located iscompletely overlapped with the vertical projection of the first activelayer 121 on the plane where the base substrate 11 is located is used asan example, which is not limited in an embodiment of the presentdisclosure as long as the first organic area 14 is disposed so that thebendability of the display panel can be improved and the crack in theinorganic material can be blocked.

The display panel 10 may further include, in part, a display area AA anda non-display area NAA. The non-display area NAA is located on at leastone side of the display area AA. In FIG. 1 , the case where thenon-display area NAA is located on one side of the display area AA isused as an example. The first organic area 14 is located in the displayarea AA so that it can be ensured that the first organic area 14improves the bendability in the display area AA while the crack in theinorganic material can be blocked from further spreading in the displayarea AA. In an embodiment, the display area AA may include multiplesub-pixels (not shown in the figure), each sub-pixel may include alight-emitting unit and a pixel circuit (not shown in the figure) thatdrives the light-emitting unit to emit light, and the pixel circuit mayinclude multiple transistors (not shown in the figure). The firsttransistor 12 may be one of the transistors in the pixel circuit.Alternatively, the first transistor 12 may also be an element in otherstructures. For example, the first transistor 12 may be one of thetransistors in a gate drive circuit (not shown in the figure), or thefirst transistor 12 may be one of the transistors in a shorting bar (notshown in the figure), or the first transistor 12 may be one of thetransistors in the multiplex output selection circuit. An embodiment ofthe present disclosure does not limit the specific existence form of thefirst transistor 12.

In an embodiment, the base substrate 11 may be a flexible base substrateor a rigid base substrate, which is not limited in an embodiment of thepresent disclosure. In the case where the base substrate 11 is aflexible substrate, the base substrate 11 may include a polyimidesubstrate so that it can be ensured that the flexible substrate has goodhigh-temperature resistance and a good insulation performance; and thebase substrate 11 may include one layer of polyimide substrate or twolayers of polyimide substrates, which is also not limited in anembodiment of the present disclosure. In the case where the basesubstrate 11 includes one layer of polyimide substrate, the basesubstrate 11 is simple in structure and preparation process, which isbeneficial to achieve the design requirements of the base substrate 11and the entire display panel for lightweight and thinness. In anotherembodiment, since the polyimide substrate is generally prepared on arigid substrate, after the pixel circuit and the light-emitting elementare prepared on the base substrate 11, the rigid substrate is generallystripped and removed through the laser lift-off technique. The polyimidesubstrate may be damaged when the rigid substrate is removed through thelaser lift-off technique. Therefore, in the case where the basesubstrate 11 includes two layers of polyimide substrates, for example,the base substrate 11 includes a first polyimide substrate and a secondpolyimide substrate, a buffer layer is disposed between the firstpolyimide substrate and the second polyimide substrate, the firstpolyimide substrate is prepared on the rigid substrate, and the pixelcircuit and the light-emitting element are prepared on the secondpolyimide substrate. Even if the first polyimide substrate may bedamaged when the rigid substrate is removed through the laser lift-offtechnique, the integrity of the second polyimide substrate can still beguaranteed, and thus the integrity of the entire display panel can beguaranteed. In FIG. 1 , only the case where the base substrate 11 is aflexible substrate and includes a first flexible substrate 111 and asecond flexible substrate 113, and an insulating layer 112 that islocated between the first flexible substrate 111 and the second flexiblesubstrate 113 is used as an example, where the first flexible substrate111 and the second flexible substrate 113 are polyimide substrates.

As described above, a display panel provided in an embodiment of thepresent disclosure includes a first transistor that includes a firstactive layer, a first source, and a first drain. The display panelfurther includes, in part, a planarization layer located on one side ofthe first source facing away from the first active layer. A firstorganic area is added to the display area between the film layer wherethe first planarization layer is located and the film layer where thefirst active layer is located. An insulating layer in the first organicarea is made of organic material. Since the Young's modulus of theorganic material is relatively small and the organic material has a goodbendability, compared with the related art, in the solution provided inembodiments of the present disclosure, on the one hand, the bendabilityof the display panel can be improved, and thus the bending stress can beavoided or reduced; on the other hand, if a crack occurs in theinorganic material, the crack can end at the interface between theinorganic material and the organic material, or even if the crackextends into the organic material, as long as the first organic area islocated on the extension path of the crack, the organic material in thefirst organic area can block the crack in the inorganic material, andthus prevent or slow the spread of the crack. In this manner, the goodbendable display effect of the display panel can be achieved.

FIG. 2 is a structure view of a display panel according to anotherembodiment of the present disclosure. As shown in FIG. 2 , at least oneinsulating layer 15 and a first organic area 14 are provided between thefilm layer where the first active layer 121 is located and the basesubstrate 11, and an insulating layer in the first organic area 14 ismade of organic material.

In an embodiment, the first organic area 14 is located between the filmlayer where the first active layer 121 is located and the base substrate11, and the insulating layer in the first organic area 14 is made oforganic material. Therefore, the first organic area 14 is disposedbetween the film layer where the first active layer 121 is located andthe base substrate 11 so that the bendability of the display panel canbe improved while the crack in the inorganic material can be blockedfrom spreading in the display area AA. It is to be noted that in thecase where the base substrate 11 includes a flexible base substrate, theorganic material in the first organic area 14 is different from theflexible base substrate and the first organic area 14 has a differentstructure from the flexible base substrate.

FIG. 3 is a structure view of a display panel according to anotherembodiment of the present disclosure. As shown in FIG. 3 , in thedirection perpendicular to the base substrate 11, the first organic area14 penetrates the insulating layer in contact with the first activelayer 121, and the first organic area 14 is in contact with theplanarization layer 13.

In the embodiment shown in FIG. 3 , the first organic area 14 penetratesthe insulating layer in contact with the first active layer 121, and thefirst organic area 14 is in contact with the planarization layer 13,that is, the first organic area 1 penetrates all the insulating layersbetween the planarization layer 13 and the first active layer 121 sothat the bendability of the display panel can be fully improved, and thebendability of the display panel can be fully ensured. Moreover, thefirst organic area 1 penetrates all the insulating layers between theplanarization layer 13 and the first active layer 121 so that the firstorganic area 14 can prevent the crack generated in any layer between theplanarization layer 13 and the first active layer 121 from continuing tospread in the display area AA. In this manner, the good stability of thedisplay panel can be ensured. Further, the first organic area 14 isdisposed to be in contact with the planarization layer 13, and theplanarization layer 13 and the first organic area 14 are prepared at thesame time, so that it can be ensured that the display panel is simple instructure preparation process.

Referring to FIG. 1 , at least one first inorganic area 16 is furtherprovided between the film layer where the first active layer 121 islocated and the planarization layer 13, and the insulating layer in thefirst inorganic area 16 is made of inorganic material.

In the shown in FIG. 1 , due to the high compactness of the inorganicmaterial and the high water-and-oxygen blocking property of theinorganic material, at least one first inorganic area 16 is disposedbetween the film layer where the first active layer 121 is located andthe planarization layer 13, and the inorganic material is disposed inthe first inorganic area 16. In this manner, film layers sensitive towater and oxygen are protected and isolated from water and oxygenthrough the inorganic material so that the film layers sensitive towater and oxygen are protected from water and oxygen corrosion, and thusit can be ensured that the film layers sensitive to water and oxygenhave a stable performance, which further ensures the stable performanceof the display panel.

Referring to FIG. 1 , in the direction perpendicular to the basesubstrate 11 (the X direction as shown in the figure), the firstinorganic area 16 is located between the film layer where the firstactive layer 121 is located and the first organic area 14, and at leastone inorganic layer is provided between the first organic area 14 andthe film layer where the first active layer 121 is located.

In an embodiment, the first inorganic area 16 is located between thefilm layer where the first active layer 121 is located and the firstorganic area 14, and the first active layer 121 is protected from waterand oxygen through the first inorganic area 16. In this manner, it canbe ensured that the first active layer 121 is protected from water andoxygen corrosion and the first active layer 121 has a stableperformance, which further ensures the stable performance of the displaypanel.

Referring to FIG. 1 , in the direction perpendicular to the basesubstrate 11 (the X direction as shown in the figure), the length of thefirst organic area 14 is H1, the sum of the thicknesses of the inorganiclayers between the first organic area 14 and the film layer where thefirst active layer 121 is located is H2, and H2≥½×H1.

In an embodiment, since the inorganic layer between the first organicarea 14 and the film layer where the first active layer 121 is locatedcan protect the first active layer 121 from water and oxygen, to ensurea high water and oxygen protection effect, the thicknesses of theinorganic layers between the first organic area 14 and the film layerwhere the first active layer 121 is located can be reasonablyconfigured. For example, in the direction perpendicular to the basesubstrate 11 (the X direction as shown in the figure), the length H1 ofthe first organic area 14 and the sum H2 of the thicknesses of theinorganic layers between the first organic area 14 and the film layerwhere the first active layer 121 is located satisfy H2≥½×H1. In thismanner, the thicknesses of the inorganic layers between the firstorganic area 14 and the film layer where the first active layer 121 islocated are not too thin, and the water and oxygen protection effect isgood.

It is to be noted that the length H1 of the first organic area 14 andthe sum H2 of the thicknesses of the inorganic layers between the firstorganic area 14 and the film layer where the first active layer 121 islocated satisfy the conditon H2≥½×H1. Here only ½ is used as an examplefor description. For example, the length H1 of the first organic area 14and the sum H2 of the thicknesses of the inorganic layers between thefirst organic area 14 and the film layer where the first active layer121 is located may satisfy the conditon H2=⅔×H1, or H2=¾×H1, and anembodiment of the present disclosure does not limit the specific valueas long as it is ensured that the thicknesses of the inorganic layersbetween the first organic area 14 and the film layer where the firstactive layer 121 is located are not too thin and the water and oxygenprotection effect is good.

FIG. 4 is a structure view of a display panel according to anotherembodiment of the present disclosure. As shown in FIG. 4 , in thedirection perpendicular to the base substrate 11 (the X direction asshown in the figure), the first inorganic area 16 is located between thefilm layer where the first gate 122 is located and the first organicarea 14, and at least one inorganic layer is provided between the firstorganic area 14 and the film layer where the first gate 122 is located.

In an embodiment, the first inorganic area 16 is located between thefilm layer where the first gate 122 is located and the first organicarea 14, and the first gate 122 is protected from water and oxygenthrough the first inorganic area 16. In this manner, it can be ensuredthat the first gate 122 is protected from water and oxygen corrosion andthe first gate 122 has a stable performance, which further ensures thestable performance of the display panel.

In another embodiment, in the direction perpendicular to the basesubstrate 11 (the X direction as shown in the figure), the length of thefirst organic area 14 is H1, the sum of the thicknesses of the inorganiclayers between the first organic area 14 and the film layer where thefirst gate 122 is located is H3, and H3≥½×H1.

In an embodiment, since the inorganic layers between the first organicarea 14 and the film layer where the first gate 122 is located canprotect the first gate 122 from water and oxygen, to ensure a good waterand oxygen protection effect, the thicknesses of the inorganic layersbetween the first organic area 14 and the film layer where the firstgate 122 is located can be reasonably configured. For example, in thedirection perpendicular to the base substrate 11 (the X direction asshown in the figure), the length H1 of the first organic area 14 and thesum H3 of the thicknesses of the inorganic layers between the firstorganic area 14 and the film layer where the first gate 122 is locatedsatisfy the conditon H3≥½×H1. In this manner, the thicknesses of theinorganic layers between the first organic area 14 and the film layerwhere the first gate 122 is located are not too thin, and the water andoxygen protection effect is good.

It is noted that the length H1 of the first organic area 14 and the sumH3 of the thicknesses of the inorganic layers between the first organicarea 14 and the film layer where the first gate 122 is located satisfythe conditon H3≥½×H1. Here only ½ is used as an example for description.For example, the length H1 of the first organic area 14 and the sum H3of the thicknesses of the inorganic layers between the first organicarea 14 and the film layer where the first gate 122 is located maysatisfy H3=⅔×H1, or H3=¾×H1, and an embodiment of the present disclosuredoes not limit the specific value as long as it is ensured that thethicknesses of the inorganic layers between the first organic area 14and the film layer where the first gate 122 is located are not too thinand the water and oxygen protection effect is good.

FIG. 5 is a structure view of a display panel according to anotherembodiment of the present disclosure. As shown in FIG. 5 , in thedirection perpendicular to the base substrate 11 (the X direction asshown in the figure), the first inorganic area 16 is located between thefirst organic area 14 and the planarization layer 13, and at least oneinorganic layer is provided between the first organic area 14 and theplanarization layer 13.

In an embodiment, since the planarization layer 13 is generally preparedby using the organic material and the organic material is also providedin the first organic area 14, to avoid a decrease in the supportingcapacity caused by excessive stacking of organic materials, the firstinorganic area 16 may be disposed between the organic area 14 and theplanarization layer 13, and the first inorganic area 16 includes atleast one inorganic layer. In this manner, the good bendability of thedisplay panel can be ensured and the good supporting effect of thedisplay panel can be ensured, and thus the good stability of the displaypanel can be ensured comprehensively. In another embodiment, the firstinorganic area 16 is located between the first organic area 14 and theplanarization layer 13 so that the water and oxygen transmission channelbetween the planarization layer 13 and the first organic area 14 can beblocked, and thus water and oxygen are blocked in the planarizationlayer 13 and are prevented from further spreading into the firsttransistor 12. In this manner, it can be ensured that the firsttransistor 12 is protected from water and oxygen corrosion, and thus thestable performance of the first transistor 12 and the entire displaypanel can be ensured.

FIG. 6 is a structure view of a display panel according to anotherembodiment of the present disclosure. As shown in FIG. 6 , in thedirection perpendicular to the base substrate 11 (the X direction asshown in the figure), the first organic area 14 is in contact with theplanarization layer 13, and the organic material in the first organicarea 14 includes the same material as the planarization layer 13.

In an embodiment, since the planarization layer 13 is generally preparedby using the organic material, and the organic material is also providedin the first organic area 14, to ensure that the organic material in theplanarization layer 13 and the organic material in the first organicarea 14 have a simple preparation process, the first organic area 14 isin contact with the planarization layer 13, and the organic material inthe first organic area 14 includes the same material as theplanarization layer 13. In this manner, the organic material in theplanarization layer 13 and the organic material in the first organicarea 14 can be prepared in the same process so that it can be ensuredthat the display panel has a simple preparation process.

FIG. 7 is a structure view of a display panel according to anotherembodiment of the present disclosure. As shown in FIG. 7 , the displaypanel 10 may further include a first capacitor 17. The first capacitor17 includes a first electrode plate 171 and a second electrode plate172. In the direction perpendicular to the base substrate 11 (the Xdirection as shown in the figure), the first electrode plate 171 and thesecond electrode plate 172 are located between the planarization layer13 and the film layer where the first active layer 121 is located, andthe first electrode plate 171 is located on one side of the secondelectrode plate 172 facing away from the base substrate 11. The firstorganic area 14 is located between the first electrode plate 171 and theplanarization layer 13, and at least one inorganic layer is providedbetween the first organic area 14 and the first electrode plate 171.

In an embodiment, the display panel 10 may further include a firstcapacitor 17. The first capacitor 17 may be a storage capacitor in apixel circuit or may be an element in other structures. For example, thefirst capacitor 17 may be one capacitor structure in a gate drivecircuit (not shown in the figure), and an embodiment of the presentdisclosure does not limit the specific existence form of the firstcapacitor 17. The first capacitor 17 includes a first electrode plate171 and a second electrode plate 172. The first electrode plate 171 andthe second electrode plate 172 are both located between the first activelayer 121 and the planarization layer 13, the first organic area 14 islocated between the first electrode plate 171 and the planarizationlayer 13, and at least one inorganic layer is provided between the firstorganic area 14 and the first electrode plate 171. In this manner, whilethe bendability of the display panel is improved, water and oxygen canbe blocked through the at least one inorganic layer so that the firstcapacitor 17 can be protected from water and oxygen corrosion, thestable performance of the first capacitor 17 can be ensured, and thus itcan be ensured that the overall performance of the display panel isstable.

FIG. 8 is a structure view of a display panel according to anotherembodiment of the present disclosure. As shown in FIG. 8 , in thedirection perpendicular to the base substrate 11, the first organic area14 is located in an area outside the first transistor 12, and the firstorganic area 14 is not overlapped with the first transistor 12.

Inthis manner, in a direction perpendicular to the X direction shown inthe figure, the area where the first transistor 12 is located hascontinuous organic materials so that the bendability of the area wherethe first transistor 12 is located can be further improved, and thus thegood bendability of the display panel can be ensured.

As shown in FIG. 11 , in thedirection perpendicular to the base substrate 11, the first organic area14 extends to the base substrate 11, the base substrate 11 is made ofpolyimide, and at least one organic layer is provided between the filmlayer where the first active layer 121 is located and the base substrate11.

In the embodiment shown in FIG. 11 , the display panel 10 may furtherinclude a buffer layer 18 located between the film layer where the basesubstrate 11 is located and the film layer where the first active layer121 is located. The buffer layer 18 may be the insulating layer 15 inFIG. 2 . In the direction perpendicular to the base substrate 11, thefirst organic area 14 extends to the base substrate 11, which may beunderstood as follows: at least part of the buffer layer 18 serves aspart of the first organic area 14 and at least part of the buffer layer18 is an organic layer. In this manner, the bendability of the displaypanel can be further improved, and the good bendability of the displaypanel can be ensured.

In another embodiment, the base substrate 11 may be a flexible basesubstrate, the base substrate 11 may include a polyimide substrate, andthe base substrate 11 may include one layer of polyimide substrate ortwo layers of polyimide substrates, which is also not limited in anembodiment of the present disclosure. In FIG. 11 , only the followingcase is described: the base substrate 11 is a flexible substrate andincludes a first flexible substrate 111, a second flexible substrate113, and an insulating layer 112 that is located between the firstflexible substrate 111 and the second flexible substrate 113. The firstflexible substrate 111 and the second flexible substrate 113 are made ofpolyimide.

At least oneorganic layer is provided between the film layer where the first activelayer 121 is located and the base substrate 11. In this manner, thebendability of the display panel can be fully improved, and the goodbendability of the display panel can be ensured.

FIG. 12 is a structure view of a display panel according to anotherembodiment of the present disclosure. As shown in FIG. 12 , in thedirection perpendicular to the base substrate 11 (the X direction asshown in the figure), a second organic area 19 is further providedbetween the base substrate 11 and the planarization layer 13, and theinsulating layer in the second organic area 19 is made of organicmaterial.

In the shown in FIG. 12 , the display panel 10 further includes, inpart, a second organic area 19 located between the film layer where thebase substrate 11 is located and the planarization layer 13, and theinsulating layer in the second organic area 19 is made of organicmaterial. Based on the first organic area 14, a second organic area 19is added, and the first organic area 14 and the second organic area 19cooperate to further improve the bendability of the display panel.Further, with continued reference to FIG. 12 , since the organicmaterial is disposed in the first organic area 14 and the organicmaterial is disposed in the second organic area 19, to avoid a decreasein the supporting capacity caused by excessive stacking of organicmaterials, at least one inorganic layer may be provided between thefirst organic area 14 and the second organic area 19 in the directionperpendicular to the base substrate 11. In this manner, the goodbendability of the display panel can be ensured and the good supportingeffect of the display panel can be ensured, and thus the good stabilityof the display panel can be ensured comprehensively. Further, since atleast one inorganic layer is disposed between the first organic area 14and the second organic area 19 in the direction perpendicular to thebase substrate 11 (the X direction as shown in the figure), the waterand oxygen transmission channel between the first organic area 14 andthe second organic area 19 can be blocked through the at least oneinorganic layer so that the further transmission of water and oxygen inthe display panel can be avoided, and thus the good water-and-oxygenblocking effect of the display panel can be ensured.

It is noted that in the direction perpendicular to the base substrate11, the first organic area 14 may be overlapped with, or not overlappedwith the second organic area 19, which will be specifically described inthe embodiments below. Additionally, it is to be noted that the basesubstrate 11 may be a flexible base substrate such as a polyimidesubstrate, and the second organic area 19 and the flexible basesubstrate have different structures.

Referring to FIG. 12 , the direction perpendicular to the base substrate11 is used as a projection direction, and the first organic area 14 isat least partially overlapped with the second organic area 19.

As shown in FIG. 12 , the direction perpendicular to the base substrate11 is used as a projection direction, the first organic area 14 is atleast partially overlapped with the second organic area 19, which may beunderstood as follows: the vertical projection of the first organic area14 on the plane where the base substrate 11 is located is at leastpartially overlapped with the vertical projection of the second organicarea 19 on the plane where the base substrate 11 is located. In thismanner, the bendability of the display panel can be improved in thedirection perpendicular to the base substrate 11 so that the goodbendability of the display panel in the direction perpendicular to thebase substrate 11 can be ensured.

FIG. 13 is a structure view of a display panel according to anotherembodiment of the present disclosure. As shown in FIG. 13 , thedirection perpendicular to the base substrate 11 is used as a projectiondirection, the first organic area 14 is not overlapped with the secondorganic area 19, and at least one of the first organic area 14 and thesecond organic area 19 is overlapped with at least part of the firsttransistor 12.

In the embodiment shown in FIG. 13 , the direction perpendicular to thebase substrate 11 is used as a projection direction, the first organicarea 14 is not overlapped with the second organic area 19, which may beunderstood as follows: the vertical projection of the first organic area14 on the plane where the base substrate 11 is located is not overlappedwith the vertical projection of the second organic area 19 on the planewhere the base substrate 11 is located. In this manner, the bendabilityof the display panel can be improved in the direction parallel to theplane where the base substrate 11 is located so that the goodbendability of the display panel in the direction parallel to the planewhere the base substrate 11 is located can be ensured.

In the embodiment shown in FIG. 13 , at least one of the first organicarea 14 and the second organic area 19 is overlapped with at least partof the first transistor 12. In FIG. 13 , the case where the firstorganic area 14 is overlapped with at least part of the first transistor12 is used as an example for description. In this manner, thebendability of the area where the first transistor 12 is located can befurther improved, and thus the overall bendability of the display panelcan be improved.

In an embodiment, the display panel may include a first conductivestructure and a second conductive structure. At least one insulatinglayer is provided between the first conductive structure and the secondconductive structure. The second conductive structure is located on oneside of the first conductive structure facing toward the base substrate.The first conductive structure is connected to the second conductivestructure through a via. In the direction perpendicular to the basesubstrate, the first organic area and the via penetrate (i.e., extendinto) the same film layer.

In an embodiment, the display panel includes a first conductivestructure and a second conductive structure that are arranged indifferent layers. The first conductive structure is electricallyconnected to the second conductive structure through a via hole. The viaand the first organic area are implemented in the same mask process andpenetrate the same film layer so that it can be ensured that the firstorganic area and the via have a simple preparation process and thepreparation process is saved.

An example of how to configure the first organic area and the via isdescribed in detail below.

FIG. 14 is a structure view of a display panel according to anotherembodiment of the present disclosure. As shown in FIG. 14 , the firstsource 123 is connected to the first active layer 121 through a firstvia 20, and the first conductive structure 21 is electrically connectedto the second conductive structure 23 through a second via 22. The depthof the second via 22 is less than the depth of the first via 20.

As shown in FIG. 14 , the first source 123 is electrically connected tothe first active layer 121 through the first via 20. The first via 20may be a via with a relatively large depth, and the drilling process isdifficult. The depth of the second via 22 electrically connecting thefirst conductive structure 21 with the second conductive structure 22 isless than the depth of the first via 20, so that the depth of the secondvia 22 is prevented from being relatively large and it can be ensuredthat the preparation process of the second via 22 is simple. Further,since the first conductive structure 21 is connected to the secondconductive structure 23 through the second via 22, the second via 22here is the preceding via that achieves the connection between the firstconductive structure 21 and the second via 22. Since the first organicarea 14 and the second via 22 penetrate the same film layers, the depthof the first organic area 14 can be prevented from being relativelylarge, and while it can be ensured that the second via 22 and the firstorganic area 14 have a simple preparation process and deep drilling isavoided, the problem of a decrease in the supporting capacity of thedisplay panel due to the relatively deep first organic area 14 can beavoided and the simple preparation process and stable performance of thedisplay panel can be ensured.

Display panel 10 shown in FIG. 14 further includes, in part, a firstcapacitor 17 that includes a first electrode plate 171 and a secondelectrode plate 172. In the direction perpendicular to the basesubstrate 11 (the X direction as shown in the figure), the firstelectrode plate 171 and the second electrode plate 172 are locatedbetween the planarization layer 13 and the film layer where the firstactive layer 121 is located, and the first electrode plate 171 islocated on one side of the second electrode plate 172 facing away fromthe base substrate 11. The first conductive structure 21 is afirst-electrode-plate connection line 24, and the second conductivestructure 23 is the first electrode plate 17. The first-electrode-plateconnection line 24 is configured to provide a voltage signal for thefirst electrode plate 171.

The display panel may further include a first capacitor 17. The firstcapacitor 17 may be, for example, a storage capacitor in a pixelcircuit, and correspondingly, the first transistor 12 may be, forexample, a switch transistor in a pixel circuit. The output terminal(source or drain) of the switch transistor is electrically connected toone of the electrode plates of the storage capacitor and writes avoltage signal to the storage capacitor. Correspondingly, in FIG. 14 ,the first-electrode-plate connection line 24 is electrically connectedto the first source 123 or the first drain 124 of the first transistor12 and electrically connected to the first electrode plate 171, so thatthe electrical connection between the first transistor 12 and the firstcapacitor 17 can be achieved, and the first transistor 12 can provide avoltage signal for the first electrode plate 171. In another embodiment,the first-electrode-plate connection line 24 is arranged in the samelayer as the first source 123 and the first drain 124, thefirst-electrode-plate connection line 24 serves as the preceding firstconductive structure 21, the first electrode plate 171 serves as thepreceding second conductive structure 23, and the first-electrode-plateconnection line 24 is electrically connected to the first electrodeplate 171 through the second via 22. The first organic area 14 and thesecond via 22 penetrate the same film layers. In this manner, it can beensured that the preparation process of the first organic area 14matches the preparation process of the display panel and the preparationprocess of the first organic area 14 is simple.

FIG. 15 is a structure view of a display panel according to anotherembodiment of the present disclosure. As shown in FIG. 15 , the firsttransistor 12 may further include a transition source 125 and atransition drain 126. The transition source 125 is located between thefirst source 123 and the first active layer 121. The transition drain126 is located between the first drain 124 and the first active layer121. The first source 123 is connected to the transition source 125through one via. The transition source 125 is connected to the firstactive layer 121 through another via.

The first drain 124 is connected to the transition drain 126 through onevia. The transition drain 126 is connected to the first active layer 121through another via. The first source 123 is a first conductivestructure, and the transition source 125 is a second conductivestructure; or the first drain 124 is a first conductive structure, andthe transition drain 126 is a second conductive structure.

In an embodiment, in conjunction with FIG. 14 and FIG. 15 , since thefirst source 123 and the first drain 124 are directly electricallyconnected to the first active layer 121 through the via, the depth ofthe via may be relatively large, and the preparation process of the viais complicated. In an embodiment of the present disclosure, thetransition source 125 is added between the first source 123 and thefirst active layer 121, and the transition drain 126 is added betweenthe first drain 124 and the first active layer 121. The first source 123is connected to the transition source 125 through one via, and thetransition source 125 is connected to the first active layer 121 throughanother via, so that the electrical connection between the first source123 and the first active layer 121 can be achieved. The first drain 124is connected to the transition drain 126 through one via, and thetransition drain 126 is connected to the first active layer 121 throughanother via, so that the electrical connection between the first drain124 and the first active layer 121 can be achieved. In this manner, thedeep hole in the existing structure is replaced by two shallow holes sothat the preparation process of the via can be simplified and thepossible poor connection due to deep drilling can be avoided. In anotherembodiment, the first source 123 serves as the preceding firstconductive structure 21, and the transition source 125 serves as thepreceding second conductive structure 23, or the first drain 124 servesas the preceding first conductive structure 21, and the transition drain126 serves as the preceding second conductive structure 23. The viaconnecting the first source 123 with the transition source 125 or thevia connecting the first drain 124 with the transition drain 126penetrates the same film layers as the first organic area 14 so that itcan be ensured that the preparation process of the first organic area 14matches the preparation process of the display panel and the preparationprocess of the first organic area 14 is simple.

In an embodiment, the display panel 10 provided in an embodiment of thepresent disclosure may further include a first signal line 25. The firstsignal line 25 may be, for example, a data signal line or a first powersignal line. The first signal line 25 is configured to provide a datasignal or a first power signal to the pixel circuit in the displaypanel. Since the display panel is provided with multiple components, toarrange various components reasonably, the first signal line 25 may berouted flexibly. In an embodiment, the first signal line 25 includes afirst sub-signal line 251 and a second sub-signal line 252 that arearranged in different layers, and the first sub-signal line 251 isconnected to the second sub-signal line 252 through a via. In this case,the first sub-signal line 251 may be the preceding first conductivestructure 21, the second sub-signal line 252 may be the preceding secondconductive structure 23, and the via connecting the first sub-signalline 251 with the second sub-signal line 252 penetrates the same filmlayers as the first organic area 14. In this manner, it can be ensuredthat the preparation process of the first organic area 14 matches thepreparation process of the display panel and the preparation process ofthe first organic area 14 is simple.

It is noted that in FIG. 16 , only the case where the first sub-signalline 251 and the first source 123 are arranged in the same layer, andthe second sub-signal line 252 and the first gate 122 are arranged inthe same layer is used as an example, which is not limited in anembodiment of the present disclosure.

Inanother embodiment, the second active layer 262 is located on one sideof the first active layer 121 facing away from the base substrate 11. Inthis manner, the second active layer 261 can be protected from beingdamaged when the first active layer 121 is processed at a hightemperature. In another embodiment, the second gate 262 is located onone side of the first active layer 121 facing away from the basesubstrate 11, and the second transistor 26 may be a top-gate structureand/or a bottom-gate structure, which is not limited in an embodiment ofthe present disclosure.

In this manner, watervapor or oxygen in the first organic area 14 can be prevented fromentering the first transistor 12 and the second transistor 26 so thatthe stable performance of the first transistor 12 and the secondtransistor 26 can be ensured, which further ensures the stableperformance of the display panel 10.

Referring to FIG. 17 , in the direction perpendicular to the basesubstrate 11 (the X direction as shown in the figure), the first organicarea 14 is located on one side of the film layer where the second activelayer 261 is located facing away from the base substrate 11, and atleast one inorganic layer is provided between the first organic area 14and the film layer where the second active layer 261 is located.

In an embodiment, as shown in FIG. 17 , the second active layer 261includes an oxide layer, the oxide layer is relatively sensitive tohydrogen ions, water vapor, and oxygen, and hydrogen ions, water vapor,and oxygen may affect the characteristics of the second active layer261. Therefore, in the case where the first organic area 14 is locatedon one side of the film layer where the second active layer 261 islocated facing away from the base substrate 11, at least one inorganiclayer may be disposed between the first organic area 14 and the filmlayer where the second active layer 261 is located. The hydrogen ions,water vapor, and oxygen entering through the first organic area 14 canbe blocked through the at least one inorganic layer. In this manner,while it can be ensured that the first organic area 14 increases thebendability of the display panel, it can be ensured that the secondactive layer 261 is protected from corrosion caused by hydrogen ions,water vapor, and oxygen, and the stable performance of the second activelayer 261 can be ensured, thereby ensuring the stable functions of thesecond transistor 26 and the entire display panel.

In an embodiment, the first transistor 12 and the second transistor 26may be used together as a pixel circuit or as part of a pixel circuit.For example, the first transistor 12 is a switch transistor, the secondtransistor 26 is a drive transistor, and the output terminal (source ordrain) of the switch transistor is electrically connected to the gate ofthe drive transistor and writes a gate signal to the gate of the drivetransistor. Correspondingly, in FIG. 18 , the second-gate connectionline 27 is electrically connected to the first source 123 or the firstdrain 124 of the first transistor 12 and electrically connected to thesecond gate 262 of the second transistor 26. In this manner, theelectrical connection between the first transistor 12 and the secondtransistor 26 can be achieved, and a gate signal is provided to thesecond gate 262 through the first transistor 12.

In this manner, while itcan be ensured that the first organic area 14 increases the bendabilityof the display panel, it can be ensured that the preparation process ofthe first organic area 14 matches the preparation process of the displaypanel and the preparation process of the first organic area 14 issimple.

In an embodiment, the via that achieves the electrical connectionbetween the second-gate connection line 27 and the second gate 262penetrates the same film layers as the first organic area 14. In thiscase, the first organic area 14 may be overlapped with the firsttransistor 12 and/or the second transistor 26, or the first organic area14 is not overlapped with the first transistor 12 and the secondtransistor 26. In the case where the first organic area 14 is overlappedwith the first transistor 12 and/or the second transistor 26, thebendability of the area where the first transistor 12 and/or the secondtransistor 26 is located can be enhanced, the spread of the crack in thearea where the first transistor 12 and/or the second transistor 26 islocated can be prevented or slowed, and thus the good bendable displayeffect of the display panel can be achieved. In the case where the firstorganic area 14 is overlapped with neither the first transistor 12 northe second transistor 26, water vapor or oxygen in the first organicarea 14 can be prevented from entering the first transistor 12 and thesecond transistor 26 so that the stable performance of the firsttransistor 12 and the second transistor 26 can be ensured, which furtherensures the stable performance of the display panel 10. In FIG. 17 ,only the case where the first organic area 14 is overlapped with thefirst transistor 12 is used as an example for description.

FIG. 18 is a structure view of a display panel according to anotherembodiment of the present disclosure. As shown in FIG. 18 , the secondsource 263 or the second drain 264 serves as the first conductivestructure 21, and the second active layer 261 serves as the secondconductive structure 23.

In an embodiment, the second source 263 and the second drain 264 need tobe electrically connected to the second active layer 261 through vias.Therefore, the second source 263 or the second drain 264 may serve asthe preceding first conductive structure 21, the second active layer 261may serve as the preceding second conductive structure 23, and the viaconnecting the second source 263 with the second active layer 261 or thevia connecting the second drain 264 with the second active layer 261penetrates the same film layers as the first organic area 14, so thatwhile it can be ensured that the first organic area 14 increases thebendability of the display panel, it can be ensured that the preparationprocess of the first organic area 14 matches the preparation process ofthe display panel, which ensures that the preparation process of thefirst organic area 14 is simple.

In another embodiment, the via connecting the second source 263 with thesecond active layer 261, or the via connecting the second drain 264 withthe second active layer 261 penetrates the same film layers as the firstorganic area 14. In this case, the first organic area 14 may beoverlapped with the first transistor 12, or the first organic area 14may be overlapped with neither the first transistor 12 nor the secondtransistor 26. In the case where the first organic area 14 is overlappedwith the first transistor 12, the bendability of the area where thefirst transistor 12 is located can be enhanced, the spread of the crackin the area where the first transistor 12 is located can be prevented orslowed, and thus the good bendable display effect of the display panelcan be achieved. In the case where the first organic area 14 isoverlapped with neither the first transistor 12 nor the secondtransistor 26, water vapor or oxygen in the first organic area 14 can beprevented from entering the first transistor 12 and the secondtransistor 26 so that the stable performance of the first transistor 12and the second transistor 26 can be ensured, which further ensures thestable performance of the display panel 10. Further, since the secondactive layer 261 of the second transistor 26 is relatively sensitive tohydrogen ions, water vapor, and oxygen, in the case where the firstorganic area 14 is not overlapped with the second transistor 26, thefirst organic area 14 may be in direct contact with the second activelayer 261 so that hydrogen ions, water vapor, and oxygen can beprevented from interfering with the second active layer 261, and thusthe stable performance of the second transistor 26 and the entiredisplay panel can be ensured.

FIG. 19 is a structure view of a display panel according to anotherembodiment of the present disclosure. As shown in FIG. 19 , the displaypanel 10 further includes a first capacitor 17. The first capacitor 17includes a first electrode plate 171 and a second electrode plate 172.In the direction perpendicular to the base substrate 11 (the X directionas shown in the figure), the first electrode plate 171 and the secondelectrode plate 172 are located between the planarization layer 13 andthe film layer where the first active layer 121 is located, and thefirst electrode plate 171 is located on one side of the second electrodeplate 172 facing away from the base substrate 11. Afirst-electrode-plate connection line 24 serves as the first conductivestructure 21, and a first-electrode-plate connection structure 173serves as the second conductive structure 23. The first-electrode-platestructure 173 is electrically connected to the first electrode plate 171(not shown in the figure); the first-electrode-plate connection line 24is configured to provide a voltage signal for the first electrode plate171.

In an embodiment, the display panel provided in an embodiment of thepresent disclosure may further include a first capacitor 17. The firstcapacitor 17 may be, for example, a storage capacitor in a pixelcircuit, and correspondingly, the first transistor 12 may be, forexample, a switch transistor in a pixel circuit. The output terminal(source or drain) of the switch transistor is electrically connected toone of the electrode plates of the storage capacitor and writes avoltage signal to the storage capacitor. Correspondingly, in FIG. 19 ,the first-electrode-plate connection line 24 is electrically connectedto the first source 123 or the first drain 124 of the first transistor12 and electrically connected to the first-electrode-plate connectionstructure 173, and the first-electrode-plate connection structure 173 iselectrically connected to the first electrode plate 171 (not shown inthe figure), so that the electrical connection between the firsttransistor 12 and the first capacitor 17 can be achieved, and a voltagesignal is provided to the first electrode plate 171 through the firsttransistor 12. In another embodiment, the first-electrode-plateconnection line 24 is arranged in the same layer as the first source 123and the first drain 124, the first-electrode-plate connection line 24serves as the preceding first conductive structure 21, thefirst-electrode-plate connection structure 173 serves as the precedingsecond conductive structure 23, and the via connecting thefirst-electrode-plate connection line 24 with the first-electrode-plateconnection structure 173 penetrates the same film layer as the firstorganic area 14. In this manner, while it can be ensured that the firstorganic area 14 increases the bendability of the display panel, it canbe ensured that the preparation process of the first organic area 14matches the preparation process of the display panel and the preparationprocess of the first organic area 14 is simple.

In an embodiment, the via connecting the first-electrode-plateconnection line 24 with the first-electrode-plate connection structure173 penetrates the same film layers as the first organic area 14. Inthis case, the first organic area 14 may be overlapped with the firsttransistor 12, or the first organic area 14 is overlapped with neitherthe first transistor 12 nor the second transistor 26. In the case wherethe first organic area 14 is overlapped with the first transistor 12,the bendability of the area where the first transistor 12 is located canbe enhanced, the spread of the crack in the area where the firsttransistor 12 is located can be prevented or slowed, and thus the goodbendable display effect of the display panel can be achieved. In thecase where the first organic area 14 is overlapped with neither thefirst transistor 12 nor the second transistor 26, water vapor or oxygenin the first organic area 14 can be prevented from entering the firsttransistor 12 and the second transistor 26 so that the stableperformance of the first transistor 12 and the second transistor 26 canbe ensured, which further ensures the stable performance of the displaypanel 10. Further, since the second active layer 261 of the secondtransistor 26 is relatively sensitive to hydrogen ions, water vapor, andoxygen, in the case where the first organic area 14 is not overlappedwith the second transistor 26, the first organic area 14 can beprevented from penetrating the second active layer 261 so that hydrogenions, water vapor, and oxygen can be prevented from interfering with thesecond active layer 261, and thus the stable performance of the secondtransistor 26 and the entire display panel can be ensured.

In conjunction with FIG. 20 and FIG. 21 , in the displaypanel 10 provided in an embodiment of the present disclosure, the secondtransistor 26 may further include a third gate 265. The second gate 262is located on one side of the second active layer 261 facing away fromthe base substrate 11.

Alternatively, athird-gate connection line 28 serves as the first conductive structure21, the third gate 265 serves as the second conductive structure 23, andthe third-gate connection line 28 is configured to provide a gate signalfor the third gate 265.

In an embodiment, the second transistor 26 is an oxide semiconductortransistor, and the second transistor 26 is generally a double-gatetransistor. Since the volume of the second transistor 26 is relativelylarge, to reduce the volume of the second transistor 26, the secondtransistor 26 may be set as a double-gate transistor with a top-gatestructure and a bottom-gate structure. As shown in FIG. 20 and FIG. 21 ,the second transistor 26 may further include a third gate 265, thesecond gate 262 is located on one side of the second active layer 261facing away from the base substrate 11 and serves as the top gate of thesecond transistor 26, and the third gate 265 is located on one side ofthe second active layer 261 facing toward the base substrate 11 andserves as the bottom gate of the second transistor 26. In this manner,the double-gate structure design of the second transistor 26 can beachieved. As described above, the first transistor 21 serves as a switchtransistor, and the second transistor 26 serves as a drive transistor.The output terminal (source or drain) of the switch transistor iselectrically connected to the gate of the drive transistor and writes agate signal to the gate of the drive transistor. In conjunction with thedouble-gate structure design of the second transistor 26, the outputterminal of the first transistor 21 may be electrically connected to thesecond gate 262 of the second transistor 26, or the output terminal ofthe first transistor 21 may be electrically connected to the third gate265 of the second transistor 26. In an embodiment, as shown in FIG. 20 ,the second-gate connection line 27 is arranged in the same layer as thefirst source 123 and the first drain 124, the second-gate connectionline 27 serves as the preceding first conductive structure 21, thesecond gate 262 serves as the preceding second conductive structure 23,and the via that achieves the electrical connection between thesecond-gate connection line 27 and the second gate 262 penetrates thesame film layers as the first organic area 14. In this manner, while itcan be ensured that the first organic area 14 increases the bendabilityof the display panel, it can be ensured that the preparation process ofthe first organic area 14 matches the preparation process of the displaypanel and the preparation process of the first organic area 14 issimple. Alternatively, as shown in FIG. 21 , the third-gate connectionline 28 is arranged in the same layer as the first source 123 and thefirst drain 124, the third-gate connection line 28 serves as thepreceding first conductive structure 21, the third gate 265 serves asthe preceding second conductive structure 23, and the via that achievesthe electrical connection between the third-gate connection line 28 andthe third gate 265 penetrate the same film layers as the first organicarea 14. In this manner, while it can be ensured that the first organicarea 14 increases the bendability of the display panel, it can beensured that the preparation process of the first organic area 14matches the preparation process of the display panel and the preparationprocess of the first organic area 14 is simple.

In an embodiment, the via that achieves the electrical connectionbetween the second-gate connection line 27 and the second gate 262penetrates the same film layers as the first organic area 14. In thiscase, the first organic area 14 may be overlapped with the firsttransistor 12 and/or the second transistor 26, or the first organic area14 is overlapped with neither the first transistor 12 nor the secondtransistor 26. In the case where the first organic area 14 is overlappedwith the first transistor 12 and/or the second transistor 26, thebendability of the area where the first transistor 12 and/or the secondtransistor 26 is located can be enhanced, the spread of the crack in thearea where the first transistor 12 and/or the second transistor 26 islocated can be prevented or slowed, and thus the good bendable displayeffect of the display panel can be achieved. In the case where the firstorganic area 14 is overlapped with neither the first transistor 12 northe second transistor 26, water vapor or oxygen in the first organicarea 14 can be prevented from entering the first transistor 12 and thesecond transistor 26 so that the stable performance of the firsttransistor 12 and the second transistor 26 can be ensured, which furtherensures the stable performance of the display panel 10. In FIG. 20 ,only the case where the first organic area 14 is overlapped with thefirst transistor 12 is used as an example for description. In anotherembodiment, the via that achieves the electrical connection between thethird-gate connection line 28 and the third gate 265 penetrates the samefilm layers as the first organic area 14. In this case, the firstorganic area 14 may be overlapped with the first transistor 12, or thefirst organic area 14 is overlapped with neither the first transistor 12nor the second transistor 26. In the case where the first organic area14 is overlapped with the first transistor 12, the bendability of thearea where the first transistor 12 is located can be enhanced, thespread of the crack in the area where the first transistor 12 is locatedcan be prevented or slowed, and thus the good bendable display effect ofthe display panel can be achieved. In the case where the first organicarea 14 is overlapped with neither the first transistor 12 nor thesecond transistor 26, water vapor or oxygen in the first organic area 14can be prevented from entering the first transistor 12 and the secondtransistor 26 so that the stable performance of the first transistor 12and the second transistor 26 can be ensured, which further ensures thestable performance of the display panel 10. In FIG. 21 , only the casewhere the first organic area 14 is overlapped with the first transistor12 is used as an example for description. Further, since the secondactive layer 261 of the second transistor 26 is relatively sensitive tohydrogen ions, water vapor, and oxygen, in the case where the firstorganic area 14 is not overlapped with the second transistor 26, thefirst organic area 14 can be prevented from penetrating the secondactive layer 261 so that hydrogen ions, water vapor, and oxygen can beprevented from interfering with the second active layer 261, and thusthe stable performance of the second transistor 26 and the entiredisplay panel can be ensured.

The above embodiment describe the case where the first organic area 12and other structures in the display panel are arranged in the samelayer, penetrate the same film layers, and are prepared in the sameprocess. The above embodiments are merely exemplary descriptions and donot limit embodiments of the present disclosure. The other case wherethe first organic area 12 penetrates the same film layers as otherstructures in the display panel is also provided in the scope ofembodiments of the present disclosure.

FIG. 22 is a structure view of a display panel according to anotherembodiment of the present disclosure. As shown in FIG. 22 , in thedirection perpendicular to the base substrate 11, the first organic area14 is located in an area outside the first transistor 12 and the secondtransistor 26, the first organic area 14 is not overlapped with thefirst transistor 12, and the first organic area 14 is not overlappedwith the second transistor 26.

In the embodiment shown in FIG. 22 , the direction perpendicular to thebase substrate 11 is used as a projection direction, the first organicarea 14 is located in an area outside the first transistor 12 and thesecond transistor 26, that is, the vertical projection of the firstorganic area 14 on the plane where the base substrate 11 is located isoverlapped with neither the vertical projection of the first transistor12 on the plane where the base substrate 11 is located nor the verticalprojection of the second transistor 26 on the plane where the basesubstrate 11 is located so that the area where the first transistor 12is located and the area where the second transistor 26 is located areboth complete areas. In this manner, while the stable performance of thearea where the first transistor 12 is located and the area where thesecond transistor 26 is located can be ensured, the first organic area14 is added to improve the bendability of the display panel.

With continued reference to the embodiments shown in FIGS. 17 to 21 ,the direction perpendicular to the base substrate 11 is used as aprojection direction, the first organic area 14 is overlapped with atleast part of the first transistor 12, and the first organic area 14 isnot overlapped with the second transistor 26.

As shown in FIGS. 17 to 21 , the direction perpendicular to the basesubstrate 11 is used as a projection direction, the first organic area14 is overlapped with at least part of the first transistor 12, and thefirst organic area 14 is not overlapped with the second transistor 26.That is, the vertical projection of the first organic area 14 on theplane where the base substrate 11 is located is at least partiallyoverlapped with the vertical projection of the first transistor 12 onthe plane where the base substrate 11, and the vertical projection ofthe first organic area 14 on the plane where the base substrate 11 islocated is not overlapped with the vertical projection of the secondtransistor 26 on the plane where the base substrate 11 is located. Theoxide semiconductor active layer in the second transistor 26 is moresensitive to hydrogen ions, water vapor, and oxygen than the siliconactive layer in the first transistor 12. Therefore, the verticalprojection of the first organic area 14 on the plane where the basesubstrate 11 is located is at least partially overlapped with thevertical projection of the first transistor 12 on the plane where thebase substrate 11 is located so that the good bendability of the areawhere the first transistor 12 is disposed can be ensured; the verticalprojection of the first organic area 14 on the plane where the basesubstrate 11 is located is not overlapped with the vertical projectionof the second transistor 26 on the plane where the base substrate 11 islocated so that the second active layer 261 in the second transistor 26can be protected from corrosion caused by hydrogen ions, water vapor,and oxygen. In this manner, the stable performance of the second activelayer 261 can be ensured, and thus the stable functions of the secondtransistor 26 and the entire display panel can be ensured.

It is noted that the first organic area 14 is overlapped with at leastpart of the first transistor 12, which may be the cases described asfollows: the first organic area 14 is overlapped with part of the firsttransistor 12, or the first organic area 14 is overlapped with theentire the first transistor 12. In FIGS. 17 to 21 , only the case wherethe first organic area 14 is located within the area between the firstsource 123 the first drain 124, and the first organic area 14 isoverlapped with part of the first transistor 12 is used as an examplefor description rather than limitation, which is not limited by anembodiment of the present disclosure.

FIG. 23 is a structure view of a display panel according to anotherembodiment of the present disclosure, and FIG. 24 is a structure view ofa display panel according to yet another embodiment of the presentdisclosure. As shown in FIG. 23 and FIG. 24 , the first organic area 14is located between the film layer where the first active layer 121 islocated and the film layer where the second active layer 261 is located,the direction perpendicular to the base substrate 11 is used as aprojection direction, the first organic area 14 is at least partiallyoverlapped with the first transistor 12, and the first organic area 14is at least partially overlapped with the second transistor 26.

In the embodiments shown in FIG. 23 and FIG. 24 , the first organic area14 is located between the film layer where the first active layer 121 islocated and the film layer where the second active layer 261 is located.In the actual preparation process, the second active layer 261 may beprepared after the first organic area 14 is obtained. Since the secondactive layer 261 is highly sensitive to hydrogen ions, water vapor, andoxygen, the hydrogen ions, water vapor, and oxygen may affect theperformance of the second active layer 261. Therefore, the second activelayer 261 is located on one side of the first organic area 14 facingaway from the base substrate 11. The second active layer 261 is preparedafter the first organic area 14 is prepared so that it can be ensuredthat the second active layer 261 is not affected by the first organicarea 14, and thus the performance stability of the second active layer261 and the second transistor 26 can be improved. Further, the firstorganic area 14 is located between the film layer where the first activelayer 121 is located and the film layer where the second active layer261 is located so that it can be ensured that the first organic area 14is not in contact with the planarization layer 13. Therefore, the waterand oxygen transmission channel between the first organic area 14 andthe planarization layer 13 can be blocked, thereby avoiding the problemof water and oxygen corrosion caused by the first organic area 14. Inanother embodiment, the direction perpendicular to the base substrate 11is used as a projection direction, the first organic area 14 is at leastpartially overlapped with the first transistor 12, and the first organicarea 14 is at least overlapped with the second transistor 26. That is,the vertical projection of the first organic area 14 on the basesubstrate 11 is at least partially overlapped with the verticalprojections of the first transistor 12 and the second transistor 26 onthe base substrate 11. In this manner, it can be ensured that thebendability of the area where the first transistor 12 is located and thearea where the second transistor 26 is located can be improved, and thusthe overall bendability of the display panel can be improved.

In the embodiments described with reference to FIG. 23 and FIG. 24 , atleast one inorganic layer is provided between the first organic area 14and the second active layer 261.

In the embodiments shown in FIG. 23 and FIG. 24 , the second activelayer 261 includes an oxide semiconductor, the oxide semiconductormaterial is relatively sensitive to ions, water vapor, and oxygen, andhydrogen ions, water vapor, and oxygen may affect the characteristics ofthe second active layer 261. Therefore, at least one inorganic layer 33is provided between the first organic area 14 and the second activelayer 261. The hydrogen ions, water vapor, and oxygen entering throughthe first organic area 14 can be blocked through at least one inorganiclayer 33. In this manner, it can be ensured that the second active layer261 is protected from corrosion caused by hydrogen ions, water vapor,and oxygen, and the stable performance of the second active layer 261can be ensured, thereby ensuring the stable functions of the secondtransistor 26 and the entire display panel.

In an embodiment, at least one inorganic layer between the first organicarea 14 and the second active layer 261 may include a silicon oxidelayer. The silicon oxide layer has an excellent hydrogen ion blockingeffect. At least one silicon oxide layer is provided between the firstorganic area 14 and the second active source layer 261 so that thehydrogen ions entering through the first organic area 14 can besufficiently blocked. In this manner, it can be ensured that the secondactive layer 261 is protected from corrosion caused by hydrogen ions,and the stable performance of the second active layer 261 can beensured, and thus the stable functions of the second transistor 26 andthe entire display panel can be further ensured.

As described with reference to the embodiment shown in FIG. 23 , thefirst organic area 14 is in contact with the film layer where the firstactive layer 121 is located; or as shown in FIG. 24 , at least oneinorganic layer is provided between the first organic area 14 and thefirst active layer 121.

In the embodiment shown in FIG. 23 , the first organic area 14 is incontact with the film layer where the first active layer 121 is located.In this manner, the first active layer 121 can be directly used as anorganic layer so that the bendability of the first transistor 12 and theentire display panel can be further improved. As shown in FIG. 24 , atleast one inorganic layer is disposed between the first organic area 14and the first active layer 121, and the first active layer 121 isisolated from water and oxygen through at least one inorganic layer. Inthis manner, it can be ensured that the first active layer 121 isprotected from water and oxygen corrosion, the performance stability ofthe first active layer 121 can be improved, and thus the performancestability of the first transistor 12 and the entire display panel can beimproved.

FIG. 25 is a structure view of a display panel according to anotherembodiment of the present disclosure. As shown in FIG. 25 , at least oneinsulating layer and a third organic area 29 are provided between thefilm layer where the first active layer 121 is located and the filmlayer where the second active layer 261 is located. The insulating layerin the third organic area 29 is made of organic material. The directionperpendicular to the base substrate 11 is used as a projectiondirection, the third organic area 29 is at least partially overlappedwith the second transistor 26, and in the direction perpendicular to thebase substrate 11 (the X direction as shown in the figure), at least oneinorganic layer is provided between the third organic area 29 and thesecond active layer 261.

In the embodiment shown in FIG. 25 , a third organic area 29 is furtherdisposed between the film layer where the first active layer 121 islocated and the film layer where the second active layer 261 is located,the vertical projection of the third organic area 29 on the plane wherethe base substrate 11 is located is at least partially overlapped withthe vertical projection of the second transistor 26 on the plane wherethe base substrate 11 is located, and the third organic area 29 isfilled with organic material. In this manner, the bendability of thearea where the second transistor 26 is located can be improved throughthe third organic area 29. In another embodiment, at least one inorganiclayer is disposed between the third organic area 29 and the secondactive layer 261, and the second active layer 261 is isolated fromhydrogen ions, water, and oxygen through at least one inorganic layer.In this manner, it can be ensured that the second active layer 261 isprotected from corrosion caused by hydrogen ions, water vapor, andoxygen, the performance stability of the second active layer 261 can beimproved, and thus the performance stability of the second transistor 26and the entire display panel can be improved.

In another embodiment, the third organic area 29 is located between thefilm layer where the first active layer 121 is located and the filmlayer where the second active layer 261 is located so that it can beensured that the third organic area 29 is not in contact with theplanarization layer 13. Therefore, the water and oxygen transmissionchannel between the first organic area 14 and the planarization layer 13can be blocked, thereby avoiding the problem of water and oxygencorrosion caused by the third organic area 29.

With continued reference to FIG. 25 , the vertical projection of thefirst organic area 14 on the plane where the base substrate 11 islocated is at least partially overlapped with the vertical projection ofthe first transistor 12 on the plane where the base substrate 11 islocated, and the bendability of the area where the first transistor 12is located can be improved through the first organic area 14.

In another embodiment, the first organic area 14 is not in contact withthe third organic area 29 in the Y direction shown in the figure. The Ydirection may be the direction in which the first transistor 12 pointsto the second transistor 26, that is, the first organic area 14 and thethird organic area 29 are disposed independently. On the one hand, thefollowing case can be avoided: a large area where the organic materialis disposed is formed due to the continuous connection of the firstorganic area 14 and the third organic area 29, and thus the supportingeffect of the display panel is reduced. On the other hand, the firstorganic area 14 corresponds to the first transistor 12, and the firstorganic area 14 only needs to satisfy the relevant film layer design ofthe first transistor 12; the third organic area 29 corresponds to thesecond transistor 26, and the third organic area 29 only needs tosatisfy the relevant film layer design of the second transistor 26. Inthis manner, the highly-independent configuration and flexiblearrangements of the first organic area 14 and the third organic area 29can be ensured; and the following case can be avoided: when the firsttransistor 12 and the second transistor 26 are provided with a commonorganic area, the common organic area needs to satisfy the film layerdesigns of the first transistor 12 and the second transistor 26, andthus multiple restrictions on the arrangement of the common organic areaexist and the arrangement of the common organic area is single.

FIG. 26 is a structure view of a display panel according to anotherembodiment of the present disclosure. As shown in FIG. 26 , at least oneinsulating layer and a fourth organic area 30 are further providedbetween the base substrate 11 and the film layer where the first activelayer 121 is located. The insulating layer in the fourth organic area 30is made of organic material, and the base substrate 11 is made ofpolyimide. The direction perpendicular to the base substrate 11 is usedas a projection direction, and the fourth organic area 30 is at leastpartially overlapped with the second transistor 26.

In the embodiment shown in FIG. 26 , at least one insulating layer and afourth organic area 30 are further provided between the base substrate11 and the film layer where the first active layer 121 is located, thevertical projection of the fourth organic area 30 on the plane where thebase substrate 11 is located is at least partially overlapped with thevertical projection of the second transistor 26 on the plane where thebase substrate 11 is located, and the fourth organic area 30 is filledwith organic material. In this manner, the bendability of the area wherethe second transistor 26 is located can be improved through the fourthorganic area 30. In another embodiment, the base substrate 11 may be aflexible substrate and may include one layer of polyimide flexiblesubstrate or two layers of polyimide flexible substrates. In FIG. 26 ,the case where the base substrate 11 includes a first flexible substrate111, a second flexible substrate 113, and an insulating layer 112located between the first flexible substrate 111 and the second flexiblesubstrate 113 is used as an example for description, where the firstflexible substrate 111 and the second flexible substrate 113 arepolyimide flexible substrates Moreover, the organic material in thefourth organic area 30 is different from the flexible base substrate andthe fourth organic area 30 has a different structure from the flexiblebase substrate.

FIG. 27 is a structure view of another display panel according toanother embodiment of the present disclosure. As shown in FIG. 27 , thenon-display area NAA of the display panel 10 includes at least oneinorganic layer, the at least one inorganic layer includes a firstgroove 31, and the first groove 31 is filled with organic material. Inthe direction perpendicular to the base substrate 11 (the X direction asshown in the figure), the first groove 31 penetrates the same filmlayers as the first organic area 14.

In the embodiment shown in FIG. 27 , the non-display area NAA of thedisplay panel 10 is provided with a first groove 31. The first groove 31may penetrate at least one inorganic layer, and the first groove 31 isat least partially filled with organic material. Since the Young'smodulus of the organic material is relatively small and the bendabilityof the organic material is good, the first groove 31 is formed in theinorganic layer, and the first groove 31 is at least partially filledwith organic material. In this manner, on the one hand, the bendabilityof the non-display area NAA can be improved; on the other hand, if acrack occurs in the inorganic material, the organic material in thefirst groove 31 can block the crack in the inorganic material, and thusprevent or slow the crack from spreading to the display area AA.

In the embodiment described with reference to FIG. 27 , in the directionperpendicular to the base substrate 11 (the X direction as shown in thefigure), the first groove 31 penetrates the same film layers as thefirst organic area 14.

In another embodiment, the non-display area NAA may include a bendingarea (not shown in the figure), and the first groove 31 may be disposedin the bending area, thereby further improving the bendability of thebending area.

FIG. 28 is a structure view of a display panel according to anotherembodiment of the present disclosure. As shown in FIG. 28 , the displaypanel 10 includes a first metal layer 32, and the first metal layer 32is located on one side of the planarization area 13 facing away from thebase substrate 11. The direction perpendicular to the base substrate 11is used as a projection direction, and the first metal layer 32 is atleast partially overlapped with the first organic area 14.

In the embodiment shown in FIG. 28 , the display panel 10 may furtherinclude a first metal layer 32. The first metal layer 32 is located onone side of the planarization layer 13 facing away from the basesubstrate 11. The first metal layer 32 may be, for example, a transitionmetal between the positive electrode of a light-emitting element and theoutput terminal (source or drain) of a transistor. The positiveelectrode of the light-emitting element is electrically connected to thefirst metal layer 32, and the first metal layer 32 is electricallyconnected to the output terminal of the transistor, so that the poorconnection between the positive electrode and the output terminal of thetransistor due to deep drilling can be avoided. The first metal layer 32may, for example, transmit a first voltage signal and be connected inparallel with the first voltage signal wiring in other film layers sothat the transmission impedance of the first voltage signal can bereduced. The first metal layer 32 may also be other types of wiring. Forexample, in the case where the pixel circuit includes both a P-typetransistor and an N-type transistor, the first metal layer 32 may serveas the scan line wiring layer of one of the preceding types oftransistors, which will not be exemplarily described by an embodiment ofthe present disclosure one by one. Since the first metal layer 32 islocated on one side of the planarization layer 13 facing away from thebase substrate 11, and the first metal layer 32 is generally alarge-area covering wiring. In this manner, the first metal layer 32 mayserve as a water-and-oxygen blocking layer of the planarization layer 13to block the external water and oxygen from entering the planarizationlayer. In another embodiment, the vertical projection of the first metallayer 32 on the plane where the base substrate 11 is located is at leastpartially overlapped with the vertical projection of the first organicarea 14 on the plane where the base substrate 11 is located. The firstmetal layer 32 may block water and oxygen from entering theplanarization layer 13. Therefore, the water and oxygen can be blockedfrom entering the first organic area 14 where the vertical projection ofthe first organic area 14 is overlapped with the vertical projection ofthe first metal layer 32, more water and oxygen can be prevented fromentering the first organic area 14, and thus the overallwater-and-oxygen blocking capacity of the display panel can be improved.
